Title:
POWER CONVERSION DEVICE, MOTOR CONTROL SYSTEM, AND PARAMETER SETTING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/111395
Kind Code:
A1
Abstract:
The purpose of the present invention is to simply and suitably adjust complicated parameters of a power conversion device. In order to achieve the purpose, this power conversion device has: an alternating current conversion unit; a detector that detects an output current, direct current voltage, and temperature; an input/output unit; and a control unit. The control unit is provided with: a motor control unit that controls the alternating current conversion unit; an operation instruction/parameter setting unit that converts the operation instructions and parameters; an information management unit; an input/output control unit; and a detection unit that acquires data from the detector. The operation instruction/parameter setting unit outputs set parameters and characteristic data to the information management unit, the information management unit acquires, from an information server, parameter information associated with the operation instructions, and parameter information with respect to an operation instruction change quantity, said parameter information being needed for adjustment, and the operation instruction/parameter setting unit converts the operation instructions inputted to the input/output unit into parameters using the data acquired by means of the detection unit, and information obtained from the information management unit, and sets the parameters in the motor control unit.
